Improved Renormalization of Lattice Operators: A Critical Reappraisal
M. Crisafulli, V. Lubicz, A. Vladikas
We systematically examine various proposals which aim at increasing the accuracy in the determination of the renormalization of two-fermion lattice operators. We concentrate on thr…
A High Statistics Lattice Calculation of Heavy-Light Meson Decay Constants
C. R. Allton, L. Conti, M. Crisafulli +3
We present a high statistics study of the D- and B-meson decay constants. The results were obtained by using the Clover and Wilson lattice actions at two different values of the la…
Chiral behaviour of the lattice -parameter with the Wilson and Clover Actions at
M. Crisafulli, A. Donini, V. Lubicz +4
We present results for the kaon -parameter from a sample of configurations using the Wilson action and configurations using the SW-Clover action, on a $18^3 \t…
First Lattice Calculation of The B-meson Binding and Kinetic Energies
M. Crisafulli, V. Gimenez, G. Martinelli +1
We present the first lattice calculation of the B-meson binding energy $\labar$ and of the kinetic energy of the heavy-quark inside the pseudoscalar B-meson. This calc…
Quenched -parameter with the Wilson and Clover actions at
M. Crisafulli, A. Donini, V. Lubicz +17
We present results for the Kaon parameter from a sample of configurations using the Wilson action and configurations using the Clover action, on a …
RESULTS FOR THE B-MESON DECAY CONSTANT FROM THE APE COLLABORATION
C. R. Allton, M. Crisafulli, V. Lubicz +4
The decay constant for the B-meson in the static limit is calculated using the Wilson and clover actions at various lattice spacings. We show that both the contamination of our res…
